Description

Technical Field

[0001] This application relates to the field of electromechanical construction technology, and in particular to a support device for erecting a construction platform for installing positioning bars in stator assembly. Background Technology

[0002] In the construction of conventional hydropower stations, the on-site assembly of large generator stators is a crucial and complex construction process. As the core component of the generator set, the stator is characterized by its large size and precise structure. Its assembly work includes stator frame assembly, core stacking, winding installation, welding, and magnetization testing, which typically requires long-term, multi-disciplinary, and meticulous work inside and at high altitudes around the stator.

[0003] To meet the demands of these high-altitude operations, a stable, reliable, adjustable, and widely covered construction platform must be erected around the stator. Currently, the industry commonly uses traditional scaffolding systems as the supporting structure for the stator assembly and positioning bar installation platform, and also employs temporary relocation structures fixed by welding. During construction, this method of scaffolding erection and the use of welded temporary relocation structures are slow, occupy a large area, and have poor construction flexibility. Furthermore, scaffolding erection is constrained by site conditions; some locations are limited, and the erection positions cannot meet the requirements of the construction work, resulting in low construction efficiency. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a support device for erecting a construction platform for installing positioning bars in stator assembly, which can quickly erect the on-site construction platform and effectively save installation time.

[0005] This application provides a support device for erecting a construction platform for installing positioning ribs in stator assembly, comprising: a clamping component, an extension component, a partition, and a sleeve. A partition is provided between the clamping component and the extension component, and the interval distance is adjusted based on the partition. Bolts pass through the clamping component, the extension component, and the partition to form a U-shaped clamping structure. The clamping structure is used to clamp the stator base ring plate. A sleeve is fixedly provided at the end of the extension component, and the sleeve is used to insert and connect the guardrail support leg.

[0006] It is equipped with partitions of various thicknesses, and the thickness of the partitions is adjusted based on the thickness of the stator frame ring plate at a fixed position.

[0007] The clamping component, the extension component, and the partition plate are provided with four corresponding connection holes. Four sets of bolts pass through the connection holes and are connected by nuts. Flat washers and elastic washers are provided between the nuts and the extension component.

[0008] The technical solution provided in this application may include the following beneficial effects: This application provides a support device for erecting a construction platform for installing positioning ribs in stator assembly. The device is easy and quick to assemble and disassemble, requiring no complex erection or welding procedures. It can be directly clamped to the target height of the stator base ring plate, quickly completing the support and fixation, significantly reducing the time cost of platform erection and dismantling. It is not overly constrained by site space conditions, flexibly adapting to the needs of different work positions around the stator, avoiding the problem of "inaccurate erection position" common with traditional scaffolding, reducing waiting and adjustment time, and improving overall construction efficiency. It does not require a large area to occupy around the stator, solving the drawback of "large area occupation" of traditional scaffolding, reserving sufficient space for simultaneous work inside and around the stator, and improving the coordination of on-site construction.

Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0014] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0015] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0016] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-4 The diagram shows a support device for erecting a construction platform for installing positioning ribs in stator assembly, comprising: a clamping member 3, an extension member 2, a partition plate 4, and a sleeve. A partition plate 4 is provided between the clamping member 3 and the extension member 2, and the interval distance is adjustable based on the partition plate 4. The partition plate 4 is provided with various thicknesses, and its thickness is adjusted based on the thickness of the stator base ring plate at a fixed position.

[0019] Bolt 7 passes through clamping member 3, extension member 2, and partition plate 4 to form a U-shaped clamping structure. The clamping structure is used to clamp the stator base ring plate. A sleeve is fixedly installed at the end of extension member 2. The sleeve is used to insert and connect the guardrail support leg. Clamping member 3, extension member 2, and partition plate 4 have four corresponding connecting holes. Four sets of bolts 7 pass through the connecting holes and are connected by nuts 8. Flat washers 5 and elastic washers 6 are provided between nuts 8 and extension member 2.

[0020] If the ring plate is directly clamped onto the clamping component 3 and the extension component 2, the stress points of the channel steel and the ring plate must be precisely aligned during clamping. Without the partition plate 4 as a positioning and filling structure, the adjustment process is cumbersome, and the tightness of the bolt 7 is difficult to control, which can easily lead to damage to the components due to overtightening or failure of fixation due to loosening. Setting the partition plate 4 increases the contact area between the device and the ring plate, preventing the pressure of the channel steel on the ring plate from concentrating locally when the bolt 7 is tightened, preventing the surface of the ring plate from sinking or deforming, and also reducing wear on the stress points of the channel steel, thus extending the service life of both. Furthermore, if there is a small gap between the thickness of the ring plate and the groove of the channel steel, a "loose" state will occur after direct tightening. When the construction platform is under load or vibrates, the support device is prone to lateral slippage or vertical loosening, which seriously affects the safety of high-altitude operations. By filling the gap between the channel steel and the ring plate with the partition plate 4, and adjusting the bolt 7 for tightening, a tighter fit can be formed, preventing the support device from slipping or loosening due to vibration during construction, and ensuring the stability of the platform. The partition plate 4 serves as a positioning reference between the channel steel and the ring plate, allowing the channel steel to quickly lock into the preset position on the ring plate without repeated alignment adjustments. Combined with the adjustment of the tightness of the adjusting bolts 7, the installation efficiency is further improved.

[0021] Specifically, the support device consists of a clamping component 3, an extension component 2, a partition plate 4, and four sets of bolt assemblies made of No. 10 channel steel. The channel steel is connected to the connecting bolts 7 via the partition plate 4. The tightness of the connection can be adjusted by adjusting the connection position. The installation gap between the clamping component 3 and the extension component 2 can be adjusted by changing the thickness of the partition plate 4. A fence fixing sleeve 1 is provided at the upper front end of the extension component 2. The sleeve 1 is fixed to the channel steel by welding, which can prevent the construction platform walking plate from slipping and facilitate the installation of the construction platform fence.

[0022] When using this support device, clamping part 3 and extension part 2 are firmly connected and assembled into a whole, snapping onto the stator base ring plate at the required height, while effectively extending out to serve as a support rod for the erection platform. After the installation is stable, scaffolding and fixed protective railings can be erected on the support.

[0023] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
